Before you sign up

A private app for learning jargon well enough to use it, not just recognize it. Here's the full picture before you ask for an invite.

Reading comes first

Most tools like this center on testing, Anki lives and dies by cards due today. I wanted something reading-focused instead, closer to my own habit of reading a short article or the news than sitting down to study. Read is that: open a term, take it in, move on, no pass or fail.

I read almost every day. I also do at least one Review a day, even if it's a single term, so testing doesn't disappear, just stays secondary. Quiz comes every few days, when I want a harder check, recognizing a term among options is easier than recalling it cold, so a Quiz pass alone doesn't mean I'm done with a term. Testing is optional though, the rest of the app works fine if you only ever Read. Quiz works out of the box, no setup needed, and gets sharper if you later add your own AI API key (Google or Anthropic) so it can write better questions.

What's actually in a term

A term isn't a flashcard. Alongside the definition there's room for an example, a mental model, in-practice notes, an anti-example, and debated angles, added only when they'd actually help, plus links to related terms. See how terms are built for the full structure.

Getting terms in

I use a skill that generates jargon lists for different fields, more on that once you're in on the import page. You can also add terms one at a time, or skip building anything and browse a shared collection instead. Any collection you build can be shared with other users too, it's not a one-way street.

No due dates

Instead of a schedule, whatever you're most at risk of forgetting comes up first, so there's never a backlog waiting for you when you come back.

How it knows what you know

Known isn't something you manage by hand, it's read off how well you've actually retained a term from reading it, recalling it in Review, and recognizing it in Quiz, and it fades again if you stop practicing.

Wherever you are

Use as many or as few surfaces as you want, web, Telegram, and the desktop widget all pull from the same practice history, so switching between them doesn't reset anything.

  • Web: Read, Review, and Quiz as their own pages, and where you import or browse collections.
  • Telegram bot: Same /read, /review, /quiz as the web, plus scheduled delivery for Read if you want terms pushed to you instead of opening the app.
  • Desktop widget: Cycles random terms on your screen in the background. It doesn't log anything on its own, open one to actually read it.

Private by default

Your own collections are private until you choose to share them. Even on a shared collection, your progress and activity history stays yours, nobody else sees it.

Getting in

You don't need an account to see if the content is any good first. Browse the public collections — Agentic Development, Software Engineering, Standup, and more — and read real terms before deciding whether to request access.

It's invite-only after that, and not an instant code. You request access, an admin approves it, and you get an email with a signup link built in. If you already have an account, that same link finishes signing you in instead of starting over.
